J-Composites Features

Assists in the simulation of a variety of composite material forming processes

Fiber Reinforcement Plastic (FRP) is a key material in the advancement of weight reduction and material strengthening for a variety of industries. The applicable forming technology varies depending on the fiber reinforcement pattern and resin matrix combination. Automation of the forming process leads to shorter cycle time and cost-saving. That is why determining better forming conditions through simulation prior to the actual trial is in high demand.

J-Composites is a set of tools, which works in cooperation with the multi-purpose solver LS-DYNA, to facilitate the complex forming process and process-chain simulation of resin composite materials. It supports the shortening of development time and reducing cost for press forming and resin flow manufacturing processes.

What is J-Composites?

The J-Composites series is a set of software for facilitating process and process-chain simulation of resin composite materials. The motivation behind development is to be able to effectively simulate complex models at the design and development stages. Collaborating with the multi-purpose solver LS-DYNA, J-Composites contributes to shortened development periods and reduced cost by automatically setting up an accurate model which represents material behavior during the forming process.

J-Composites Series

The J-Composites series consists of ”Form Modeler”, a tool to set up press forming analysis, ”Compression Molding”, a tool to set up compression molding analysis, and “Fiber Mapper”, a tool to map a resin flow simulation result on to a structural mesh. More tools for supporting the simulation of various resin composite material forming processes and process-chains are in development.

Accurately predict forming defects and determine forming conditions ahead of time

J-Composites / Form Modeler is a tool for creating models for resin composite material forming simulation. It helps reduce the man-hours necessary to design composite materials with features such as auto-conversion of material experiment results into material data for simulation and auto-creation of product model from laminate configuration.
The combination with the multi-purpose nonlinear solver LS-DYNA allows simulating the material behavior during forming accurately. Based on a LS-DYNA simulation result, it is possible to predict forming defects such as wrinkles, which in turn contributes to a shortened development period and reduced cost.

Accurately predict fiber and resin deformation during compression molding

Discontinuous long-fiber reinforced plastics are receiving increasing attention for their use in compression molding, by which they can be formed into almost any shape without losing strength. JSOL has developed a simulation method for LS-DYNA that accurately predicts compression molding behaviour.

This new method uses beam elements to represent the fibers and EFG solid elements for the matrix resin. The fiber-matrix interaction is simulated using a beam-in-solid coupling method. The simulation is complex and requires both effort and knowledge to set up. Through JSOL’s know-how and experience, the software tool J-Composites / Compression Molding simplifies the process and automatically provides optimized solution parameters for a stable simulation.

Improve the accuracy of structural simulation by considering the effects of the fabrication process

The behavior during forming, especially fiber orientation, strongly affects a product's mechanical performance. ”Fiber Mapper” is a mapping tool for carrying the forming simulation result of a discontinuous fiber reinforced plastic forward to predict the effects of the forming process by using LS-DYNA.
